Sinkholes

[TNLAKEPANDA]

Here is a very interesting youtube video on sinkholes and towards the end they explain why they are happening so often now.

Enjoy...

I watching the video and starting to wonder, when the book was coming out. Sure enough, it's at the end of the video.

I am too positive a person to let this doom and gloom type of scenario to affect me. :smiley:

"Florida" sink holes are caused by running water moving the sandy soil gradually away. The water could be natural runoff, leaking water pipes or leaking culverts.

I'm also a Professional Civil Engineer. While an occasional sink hole may have a unique cause, I agree with sail33or's post.

Why Are There So Many Sinkholes in Florida? - The Atlantic (http://www.theatlantic.com/technology/archive/2014/08/why-are-there-so-many-sinkholes-in-florida/378869/)

Clint Kromhout, a geologist in the Florida Department of Environmental Protection, wrote the paper "What’s Up with All the Sinkholes?":

The bulk of Florida’s peninsula is made up carbonate rock (limestone and dolostone) overlain by variable thicknesses and mixtures of sand and clay (i.e., overburden). Carbonate rocks store and transmit groundwater. Through a slow chemical process these carbonate rocks may dissolve, resulting in karst terrain (topography). Karst terrains are characterized by sinkholes, caves (wet and dry), springs, disappearing/reappearing streams, and other land surface depressions all of which are commonly found throughout Florida.

Both natural phenomena and human activity can trigger sinkholes. Heavy rainfall, especially after a drought, and tropical storms contribute to the forming of a sinkhole, while man-made sinkholes can be prompted by heavy pumping of groundwater for agricultural protection, investigative drilling, and excavation.

So photo1902 was correct.

In fact, according to the quote above it sounds more like the slow dissolving of carbonate rocks (not necessarily with "running water") is more to blame.

But heck, what does this geologist Clint Kromhout know...all he's done is write a paper on it.

I never said he was wrong. I don't see any major discrepancies between what Photo and and sail said. If you think running water is limited to surface flow, it is not. The chemical reaction would not take place without the subsurface water flow. Groundwater would not maintain its level without the flow of water.

I did not mean my original reply to show major disagreement with anyone. I was simply supporting an engineering statement.

By the way, I guess I should write a paper. Looks like that would make me infallible.

I was trying to keep it simple for average Village readers so they can watch for things they might control at their houses. (ie. trying to help) And not publish a freaking paper on the subject.

Ummm no, that would just make you a civil engineer who wrote a paper on sinkholes....while the guy I quoted would still be a geologist who wrote a paper on sinkholes. :shrug:

Ya gotta love the title... "The Groundbreaking Truth." :D

I have observed this for myself. After a long time of not much rain, and a lot of rain happens, say upwards of 7-8 inches in a 2-3 day span, then sinkholes are much more likely to occur. I have read this; we are in the county with seventh most sinkholes in Florida. The areas toward Tampa have the most. I remember this, when sinkholes do appear, there is usually a couple of threads on this forum blaming someone for it.
Number of sinkholes by county - Here they are. (Tampa: foreclosures, insurance) - Tampa Bay - Florida (FL) -Tampa - St. Petersburg - Clearwater - City-Data Forum (http://www.city-data.com/forum/tampa-bay/1993053-number-sinkholes-county-here-they.html)

If it would rain a LOT right now, after a longish period with not much rain, we would see some sinkholes I would think.

I have also observed Polar Bear's posts on this forum for a long time. He is an intelligent person for a large furry mammal. Slow to anger, well read and articulate.

You might want to brush up on your knowledge regarding what fields of study are included in the civil engineering field. Regardless...

I and all the other Professional Engineers who might read this forum would like to express our gratitude for your gracious expression of respect.

[ColdNoMore]

I'm fully aware of the course of study for becoming a civil engineer.

I'll just stick with the geologist, whose link I posted.

Thanks. :ho:

I believe you. You just don't show it.

No one was asking for an engineer's opinion or argument. It is just a video of interest.

Al Gore received a Nobel prize for a movie on climate change. That doesn't make him an expert, either.
